That's a nice HP-1XC collection Sylvain !.
When I look to buy one HP-12C, there are a number of options, if and only if the pictures represent the actual article!!, how about this one on TAS ? : 151328796761.
It has the text on the left but is no 25th Anniversary ? You 12C Platinum has no text on the left of the display. Too many slightly different, slightly equal models
Who knows which one one gets...

Hello Alejandro,
Thank you! the model that you pointing to, is one of the two HP-12C Platinum Black and probably the one using 2x2032 who is still to my knowledge in production.

Don't forget the special units supplied with college courses, such as the University of Michigan MBA logo 12c, etc.

This piece I'm still missing in my collection.

But that's missing from your Pioneer collection. Your Voyager collection is fine - apart from missing the 15CLE and the never sold 15C+ :-)

How about the rare, blue 12C. There are only three known to exist!

I wonder how he managed to get all these. I have never seen a clear case prototype on the market.

Occasionally they pop up on eBay. Lately with mid four-figure price tags.

My full collection is here (including Sharp, Casio, etc): https://www.flickr.com/photos/keithmidso...634156167/

There are so many Voyagers! The 12C alone has so many variants - some here: https://www.flickr.com/photos/keithmidso...586986282/

Cheers, Keith

Compliments....thank-you for sharing them

EDIT: typo

You have a MK100... that's real rarity ! I also like the shaps with graphic LCD, they may not look as stunning as the 71B but surely are they nice !
